A pattern of common electrode layer is designed such that the common electrode layer is partitioned into a plurality of mutually independent self-capacitance electrodes along strip-like slits and a direction crossing the slits. The touch sensing chip can determine a touch position by detecting capacitance value variation of self-capacitance electrodes in a touch period. The in-cell touch panel can save production costs and improve production efficiency, and also can avoid light leakage caused by cutting common electrode layer and influence on display effect."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-cell touch panel and display device","description":"An in-cell touch panel and a display device are disclosed, a common electrode layer is reused as self-capacitance electrodes in accordance with self-capacitance principle.
